Benefits of technology

The invention allows for monitoring the inhomogeneity of fluid application using an infra-red camera. The vapor is very fine, making it difficult to see visually, so the camera detects changes in temperature caused by the application. This temperature distribution is a reliable measure of the inhomogeneity of the fluid application. Automation of the process monitoring is possible using simple means, as the temperature distribution can be recorded and compared with a norm. The invention is useful for producing engineered wood boards and floorboards.

Problems solved by technology

It has been proven that the vapour or spray resulting from the application is preferably very fine so that it is indeed visible, in particular in the presence of a backlight or when light is coming from the side, but that this visual detection of the vapour distribution is complex and is almost impossible to automate.

Embodiment Construction

[0058]FIG. 1 schematically depicts an engineered wood board production installation 10 that comprises a substrate production installation 12 and an applicator 14 for applying a fluid 16 to a substrate 18. At this point the substrate 18 is a pressed fibre mat and is produced by the substrate production installation 12 by scattering wood fibres that have been coated in an adhesive onto a conveyor 20.

[0059]The engineered wood board production installation 10 comprises an infra-red camera 22 in whose field of vision 23 an application area 24 lies. The application area 24 is the area of the substrate 18 that is moistened with fluid 16. A press 26 is arranged in a material flow direction behind the applicator, which presses the pressed fibre mat 18 to form an engineered wood board 27. The press 26 is a double belt press having two belts made from stainless steel that are

[0060]A cutting device may be provided behind the press 26 in the material flow direction M that cuts the resulting engi...

Abstract

A method for producing an engineered wood board. The method includes production of the substrate and application of a fluid to an application area of the substrate by means of an applicator, where the monitoring of the application occurs by means of an infra-red camera such that an inhomogeneity of the application can be detected.

Description

FIELD OF INVENTION[0001]The invention relates to a method for producing an engineered wood board with the steps (a) production of the substrate and (b) application of a fluid to an application area of the substrate by means of an applicator. In particular, the invention relates to a method for the production of an engineered wood board, especially an MDF or HDF board or a floorboard.[0002]According to a second aspect, the invention relates to an engineered wood board production installation that is designed to produce an engineered wood board, in particular an MDF or HDF board or a floorboard with (a) a substrate production installation for producing a substrate and (b) an applicator for applying a fluid to an application area of the substrate.BACKGROUND[0003]During the production of engineered wood boards, in particular within the scope of a production method for floorboards, to which the invention also relates, a substrate in the form of a fibre mat is used, which contains wooden ...
